System/Component Failed & Inspection: The vehicle suffers from recurring failures across the engine, powertrain, electronic throttle control, and exhaust gas recirculation (EGR) control systems (DTCs P0524, P0642, P2118, P022100). The vehicle is fully available for inspection upon request. Safety Risk: While driving, the vehicle suffered a complete, sudden loss of motive power on an active highway entrance ramp. The engine stalled in moving traffic with zero throttle response, creating an immediate collision hazard before requiring a tow. Confirmation by Dealer: Technicians formally confirmed these defect patterns. In May 2026, diagnostics logged major engine and emission/EGR control codes, but corporate refused goodwill repair. In August 2026, the highway stall recurred. Diagnostics confirmed active low oil pressure and throttle failure codes, which the dealer resolved by applying 4 factory ECU software updates under TSB 25-01-010H. Service personnel explicitly confirmed these engine control issues are manufacturing defects, not wear-and-tear or mileage-related. Inspections: Inspected, diagnosed, and serviced by authorized dealership service department technicians during both the May and August 2026 failure events. Warning Symptoms & History: Engine issues began at 341 miles when purchased new (settled). In May 2026, check engine lights returned with diagnostic codes for engine and EGR/emissions systems. In August 2026, total power loss occurred, preceded by check engine, forward collision camera, and radar sensor warnings.

My 2025 Mazda CX-5 has an intermittent defect that causes Android phones connected to Android Auto through the vehicle's USB-C port to unexpectedly perform a complete device reboot while the vehicle is being driven. The problem began in August 2025 after I purchased a Google Pixel 9. I initially believed the phone was defective and spent several months troubleshooting the phone. After the same problem occurred with my son's Google Pixel 10, I determined the issue was not phone-specific. I reported the problem to Mastria Mazda in March/April 2026 and returned again in May 2026. I opened a case with Mazda Customer Experience on June 4, 2026. The vehicle software has been updated, but the defect remains. The failure is random. It does not occur immediately after connecting the phone and is not associated with navigation, music, phone calls, messaging, or trip duration. It can occur once during a trip or multiple times during the same trip. The defect has been reproduced with two different phones (Google Pixel 9 and Pixel 10) using multiple USB-C cables. The same phones were then tested using wired Android Auto in another 2025 Mazda CX-5 (loaner driven for one week), a Mazda3, a Mazda CX-90, and a Tesla. The problem did not occur in any of those vehicles. My Pixel 9 also works normally in my vehicle when using wireless Android Auto. The reboots occur only through the wired USB-C Android Auto connection in my vehicle. This creates a safety hazard because Android Auto immediately disconnects, causing the sudden loss of navigation, the head-up display directions, hands-free calling, and voice commands while driving. The defect has occurred multiple times during Boston morning rush-hour traffic and while navigating a major highway interchange under construction where lane assignments had been temporarily changed. The unexpected loss of navigation and driver information at these critical moments creates a significant driver distraction and potential safety risk.

The blind spot warning went off and locked all the brakes up. We were not able to move the vehicle and could not even pull off the road out of traffic. There is no way to disable the brakes when the computer or sensors are malfunctioning. We had to get the vehicle towed.

Thankfully we are alive. We were going at speed and he attempted to pass me on the median, grass and rumble strips. He was inches away from my rear bumper, riding me. When I put the turn signal to move away from him he hit my driver’s side rear panel (side swiped), thank God it didn't turn into a pit maneuver and killed us. He then proceeded to take off. So one thing I have to say is, the vehicle has great pick up. I called 911 and went after him to get his lic plate. When I got to be about 10 car lengths or so, he slammed his brakes. Since I was on the left lane, I could not keep going left and risk going into oncoming traffic. Plus, there was a car on the right lane I slammed the brakes and rear ended him on his right rear. He had a 2021 Toyota Tacoma pick up and our hood flipped up and shattered the windshield. The hood stayed up and I was driving blind. All I did was keeping straight, not knowing where I was going and didn’t hit a vehicle, tree, embankment or sign. I went there yesterday and I have no idea how I we didn’t die. I’m so shaken up by it. When we came to a stop, there was a hole about 6 feet from my front tire. We were the victim of road rage and this person caused the accident purposely. He admitted it to the police. He said to the cop, I was slowing down traffic. I suspect with the size of his vehicle and being so close to my rear bumper, he did not see my turn signal. My major concern is the airbags did not deploy and the hood flipped open blocking my view. I was in a forum and this happened to the same model owned by someone else. I suspect this is a design flaw.

WIPERS STOP WORKING. THEY WILL FREEZE AND STOP MOVING ACROSS THE WINDSHIELD. SO FAR I CAN FIX THE PROBLEM BY TURNING THE WIPERS OFF AND THEN BACK ON. MY CONCERN IS THAT MAY NOT WORK IN THE FUTURE. ALSO, IN HEAVY RAIN AN ACCIDENT MAY HAPPEN BEFORE I CAN RESTART THE WIPERS. I BROUGHT THE CAR IN TO THE DEALERSHIP, BUT THEY COULD NOT FIND ANYTHING WRONG.

My vehicle suffered a disabling failure 325 miles from home due to an open Safety Recall campaign. The vehicle is repaired under Campaign Claim #43195279, but Hyundai Corporate is actively denying both a reunite transport tow and travel rental accommodations to retrieve the vehicle. The manufacturer is failing to provide a reasonable or accessible remedy, leaving me completely carless at home for 3 days due to an admitted safety defect with no way to retrieve my vehicle 325 miles from home.
